Sales roles are an essential part of many businesses and are likely to grow as the economy expands. However, the rate of growth is highly industry-specific, with some sales roles (such as in software as a service) likely to see extremely high growth, while others are likely to decline. Compensation for sales employees often includes commissions on successful deals, giving high-performing workers the opportunity to earn more. Specialised roles like technical sales also offer the opportunity to earn a higher salary for workers with technical skills. Customer service and communciation skills are universally valuable across sales, giving salespeople the flexibility to easily switch between companies and industries.
